1. I can make two VCP at USB HS port and FS port at the same time by Library v2.1.0.
2. Read/Write USB Disk is ok by STM32F4DISCOVERY firmware which is base on OTG Library v2.0.0, It can access any UDisk;
3. Read/Write USB Disk is not good by example of Library v2.1.0. It can only access some UDisk. For some disk , It can enumerate but stoped at GET_MAX_LUN stage.
Are there any bugs in Library v2.1.0.?
